Comment on chakra.

This is a word for wheel. It is more indirectly referred to through mention of the deities. While no images are provided with some editions, it would not have been out of place for there to be chakras present. These wheels were in some cases weapons, most likely throwing weapons. It comes up since the deific images of Brahma, Vishnu and especially Shiva are apt to have chakras. This is also mentioned to clarify the matter because in the West 'chakra' is most often meant to describe areas along the human spinal column that seem to easily 'build up energy'.
